If you want to sell coins then you can split the info or vice versa
This was my suggestion too.
Sticky the thread to Currency Exchange. Problem solved.
A resourceful thread worth sticking but that's up to moderators and admin. If you split the topic then I do not see any problem sticking the topic (scammers list part) in the exchange board too. But having something like you are seeking currency exchange and expecting it to be sticking obviously make others jealous [referring to my newly created currency exchange thread]🤪.
In a serious note, it would not look good that in a sticky thread there is an advertisement. Common-sense brother.
